Bored? Looking for things to do? No, me neither. But have some fun and look at these skulls — then identify them (taking care to note your identifications in the comments below). And then… … see if you can go that extra bit further and say something especially interesting*, since there’s lots of neat stuff going [...]

Tet Zoo readers with supernatural memories will doubtless recall the January 2012 article ‘Rigid swimmer’ and the Cretaceous Ichthyosaur Revolution (part I) [link below]. I’ll refresh your memory by telling you that the article was all about the PLoS ONE paper on Acamptonectes, a Cretaceous ophthalmosaurid ichthyosaur from the UK and Germany described by Valentin [...]

Any adventures about the more rural parts of the UK typically involve (for me, anyway) a lot of looking at the Rook Corvus frugilegus, a remarkable Old World corvid that occurs from the far western shores of the UK and France all the way east to Japan (it’s generally absent from the cold northern parts [...]

Tet Zoo regulars will remember the detailed montage I’ve produced that hopefully gives some idea of crocodylomorph diversity (Crocodylomorpha = the archosaur clade that includes modern crocodylians and all taxa closer to them than to croc-branch members of Archosauria like the aetosaurs and rauisuchians. Crocodylomorpha is basically equivalent to ‘Crocodilia’ of tradition; most members of [...]

Over the last few days, I and my friends and colleagues from the University of Southampton’s vertebrate palaeontology research group visited Lyme Regis for the 2013 Fossil Festival, a big, fun event attended by 1000s of people and by most palaeontologically- and geologically-oriented people in the southern half of the UK. There are stalls and [...]

My photography skills – if I can call them that – are pretty atrocious. While on a break in Wales recently, I managed to photograph a sequence in which a Herring gull Larus argentatus (one of our most frequently encountered gulls) swallowed a Common sea star Asterias rubens. Yeah, that’s right, get into the habit [...]

Time for a quick look at another temnospondyl group. Today, we focus on the tupilakosaurids, a group of short-limbed, blunt-skulled, long-bodied Permo-Triassic temnos. Ossified ceratobranchials, poorly ossified limbs and long and flexible bodies all suggest that they were fully aquatic though – like some other aquatic temnospondyl groups – their bones lack lateral line sulci. [...]

For over 100 years, a potentially significant dead cat has been sat in storage in a British museum. Specifically, the specimen – the lynx Ab4458 – has been at Bristol Museum and Art Gallery ever since it was added to the collections there in February 1903, and what makes it significant is that it was [...]

Mesozoic dinosaurs of several lineages famously possessed horns, frills, bony bosses, crests, frills, blah blah blah – you’ve heard all this a million times before. Pterosaurs were flamboyant creatures too. Why did these animals possess these so-called exaggerated structures? Together with Dave Hone, I’ve just published my latest missive on this issue (Hone & Naish [...]

Good news: I’ve decided to treat you all to yet another article on temnospondyls. This time we look at several (mostly) Permian groups – the sclerocephalids, archegosaurids and their relatives – that have sometimes (but not consistently) been grouped together as the Archegosauroidea or Archegosauriformes. As before, I have to note that there are strongly [...]
